Diagnostic problem code P0705 shows that a Transmission Range Sensor (TRS) input error has been obtained by the Engine Control Module (ECM) or Transmission Control Module (TCM). Also known as a pressure switch, park-neutral position switch (PNP), gear selection switch, or PRNDL input switch, this switch is called. The Transmission Range Sensor role is to indicate the position of the shift lever to the ECM or TCM. The TRS is most frequently situated on the outside of the transmission, but some are situated on the valve body inside the transmission.
If the ECM does not obtain an input, this specific problem code will be set. It will also set if the ECM receives an input that can not be logically possible: if, for example, the vehicle goes 50 MPH, but the Transmission Range Sensor tells the ECM that it is in reverse, a P0705 code will be set. There have also been instances where a TRS failed to a point where the ECM was told that it is simultaneously in more than one gear; if this is the case, it will set code P0705.
There are three kinds of Transmission Range Sensors: the Contact type, a straightforward set of switches communicating the precise position of the shifter point to the ECM. For each shifter position, this sort utilizes a distinct wire.
The Pressure Range Switch is bound to the transmission valve body. As the shift lever is shifted, it opens and closes various passages for the transmission fluid. As the gear position moves, this sort of range sensor activates and senses a distinct transmission fluid passage.
In the Transmission Range Sensor family, the Variable Resistor type is the third. It includes a sequence of resistors linked to the same output of voltage. A resistor is intended to absorb some voltage. Each equipment has in its circuit its private resistor and will be used depending on the placement of the user (PRNDL).
What is the cause of the code P0705?
Open or short in the TRS circuit Faulty TRS ECM or TCM Misadjusted shift connection Faulty transmission valve body or contaminated transmission fluid and more.
